Grimm Law Correspondence Pair Lookup

Independently verified conditioned ProtoIndoEuropean/ProtoGermanic sound correspondence, not arbitrary modern phoneme replacement. Exact independently verified context/edition key, not live or embedded reference data. Caller establishes language, dialect, method and reference context; no automatic identity or universal language-wide claim.

Description

Grimm's-law correspondences concern specified historical sound relationships.

Grimm's-law correspondences concern specified historical sound relationships.^[1]

A useful lookup preserves the conditioned forms and historical stages rather than treating spelling similarity as a sound change. The tool retrieves your supplied source-specific notice for one exact key; it contains no built-in or live reference database.

When to use Grimm Law Correspondence Pair Lookup

Use this tool to calculate or review the supplied observations under the stated rules. Specify the language variety, analysis, source edition and population or inventory definition.

How to use Grimm Law Correspondence Pair Lookup and understand its results

Specify the language variety, analysis, source edition and population or inventory definition.
Enter callerVerifiedGrimmCorrespondenceKeys, callerVerifiedGrimmCorrespondenceNotices, queryGrimmCorrespondenceKey, using the field meanings and rules below, then run the tool.
Read matchedCallerNotice, using the output meanings and calculation rules below. Confirm that the exact matched record is the one whose source and context apply.
Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.

Input field	Meaning	Value type	Requirement
callerVerifiedGrimmCorrespondenceKeys	Caller verified grimm correspondence keys	list of string	Required
callerVerifiedGrimmCorrespondenceNotices	Caller verified grimm correspondence notices	list of string	Required
queryGrimmCorrespondenceKey	Query grimm correspondence key; use the exact reference token or coordinate domain stated below	string	Required

Supply nonempty aligned unique nonblank context keys and nonblank notices, then query one exact existing key. Matching is case-sensitive without trimming or normalization. Return its original notice unchanged; unknown keys fail. No data is fetched or independently verified.

notice=notices[indexOf(keys,exactQuery)]

Use the matching field units and the exact boundary, ordering and reference rules above.

Limitations and assumptions

The language variety, analytical definitions and reference scope are supplied by the caller. No corpus, speech or complete/current linguistic registry is analyzed automatically. Reference records and their claimed verification are supplied by the caller; the tool does not retrieve or verify them.

Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Lists and matrices must be dense, without missing cells. Numeric lists allow at most 10000 entries; ordinary string lists allow at most 128 strings of 128 UTF-16 units each; numeric matrices allow at most 128 rows and 128 columns, subject to narrower requirements above.

Alternative or Complementary methods

For a related step, use High German Consonant Shift Pair Check: Historical consonant correspondences must be conditioned on the relevant sound environment and stage. For a complementary comparison, use Cognate vs Loanword Classifier: Cognates and loans involve different historical relationships between forms.
